BACKGROUND Technical Field

The present disclosure relates to surgical instruments and, moreparticularly, to an energy-based surgical instrument having multipleoperational configurations.

Background of Related Art

Energy-based surgical instruments such as bipolar electrosurgicalforceps are commonly used to treat, e.g., coagulate, cauterize and/orseal, tissue. Such forceps typically include a pair of jaw members thatcan be manipulated to grasp tissue and apply a mechanical clamping forceto the tissue. Electrodes associated with the jaw members are charged todifferent electrical potentials such that electrosurgical energy may beselectively transferred through the tissue. The combination ofelectrosurgical energy and mechanical clamping force facilitatestreating the tissue.

Some forceps are designed for in-line activation wherein, at the end ofthe actuation motion required to approximate the jaw members to grasptissue therebetween, an activation button is activated to initiate thesupply of energy to the jaw members. Still other forceps enable latchingto maintain the jaw members in an approximated position grasping tissuetherebetween. Such forceps may include a separate activation button thatis manually activated, e.g., once the jaw members are latched in theapproximated position, to initiate the supply of energy to the jawmembers. However, these operational configurations are heretoforemutually exclusive, thus requiring a surgeon to choose a device havingone or the other.

DETAILED DESCRIPTION

Referring to FIG. 1, an energy-based surgical instrument 10 is shownconfigured as a bipolar electrosurgical forceps for use in connectionwith endoscopic surgical procedures, although instrument 10 may defineany suitable configuration for use in endoscopic and/or traditional opensurgical procedures. Instrument 10 generally includes a housing 20, ahandle assembly 30, a rotating assembly 60, a trigger assembly 80, anend effector assembly 100 including first and second jaw members 110,120.

Instrument 10 further includes a shaft 12 having a distal end portion 14configured to engage end effector assembly 100 and a proximal endportion 16 that engages housing 20. Rotating assembly 60 is rotatable ineither direction to rotate shaft 12 and end effector assembly 100relative to housing 20 in either direction. Housing 20 houses theinternal working components of instrument 10.

Instrument 10 also includes an electrosurgical cable 300 that connectsinstrument 10 to an electrosurgical generator “G” or other suitableenergy source, although instrument 10 may alternatively be configured asa handheld instrument incorporating energy-generating and powercomponents thereon or therein. Cable 300 includes wires (not shown)extending therethrough, into housing 20, and through shaft 12, toultimately connect electrosurgical generator “G” to jaw member 110and/or jaw member 120 of end effector assembly 100. First and secondactivation buttons 92, 94 disposed on housing 20 are electricallycoupled between end effector assembly 100 and cable 300 so as to enablethe selective supply of energy to jaw member 110 and/or jaw member 120,e.g., upon activation of either of activation buttons 92, 94. However,other suitable electrical connections and/or configurations forsupplying electrosurgical energy to jaw member 110 and/or jaw member 120may alternatively be provided, as may other suitable forms of energy,e.g., ultrasonic energy, microwave energy, light energy, thermal energy,etc.

Instrument 10 additionally includes a knife assembly 170 operablycoupled to trigger assembly 80 and extending through housing 20 andshaft 12. One or both of jaw members 110, 120 defines a knife channel125 (FIG. 2A) configured to permit reciprocation of a knife blade 172(FIG. 2A) of knife assembly 170 therethrough, e.g., in response toactuation of trigger 82 of trigger assembly 80. Trigger assembly 80 andknife assembly 170 are described in greater detail, for example, in U.S.Pat. No. 9,655,673, which issued based upon U.S. patent application Ser.No. 14/196,066 filed on Mar. 4, 2014, the entire contents of which ishereby incorporated herein by reference.

With additional reference to FIGS. 2A and 2B, end effector assembly 100,as noted above, is disposed at distal end portion 14 of shaft 12 andincludes a pair of jaw members 110 and 120 pivotable between aspaced-apart position and an approximated position for grasping tissuetherebetween. End effector assembly 100 is designed as a unilateralassembly, e.g., wherein one of the jaw members 120 is fixed relative toshaft 12 and the other jaw member 110 is movable relative to both shaft12 and the fixed jaw member 120. However, end effector assembly 100 mayalternatively be configured as a bilateral assembly, e.g., wherein bothjaw member 110 and jaw member 120 are movable relative to one anotherand with respect to shaft 12.

Each jaw member 110, 120 of end effector assembly 100 includes anelectrically-conductive tissue-contacting surface 116, 126.Tissue-contacting surfaces 116 are positioned to oppose one another forgrasping and treating tissue. More specifically, tissue-contactingsurfaces 116, 126 are electrically coupled to the generator “G,” e.g.,via cable 300, and activation buttons 92, 94 to enable the selectivesupply of energy thereto for conduction through tissue grasped betweenjaw members 110, 120, e.g., upon activation of either of activationbuttons 92, 94. One or both of tissue-contacting surfaces 116, 126 mayinclude one or more stop members (not shown) extending therefrom todefine a minimum gap distance between electrically-conductivetissue-contacting surfaces 116, 126 in the approximated position of jawmembers 110, 120, facilitate grasping of tissue, and/or inhibit shortingbetween electrically-conductive tissue-contacting surfaces 116, 126. Thestop member(s) may be formed at least partially from anelectrically-insulative material or may be effectively insulative byelectrically isolating the stop member(s) from one or both of theelectrically-conductive tissue-contacting surfaces 116, 126.

A pivot pin 103 of end effector assembly 100 extends transverselythrough aligned apertures defined within jaw members 110, 120 and shaft12 to pivotably couple jaw member 110 to jaw member 120 and shaft 12. Acam pin 105 of end effector assembly 100 extends transversely throughcam slots defined within jaw members 110, 120 and is operably engagedwith a distal end portion of a drive bar of a drive assembly (not shown)such that longitudinal translation of the drive bar through shaft 12translates cam pin 105 relative to jaw members 110, 120. Morespecifically, distal translation of cam pin 105 relative to jaw members110, 120 urges cam pin 105 distally through the cam slots to therebypivot jaw members 110, 120 from the spaced-apart position towards theapproximated position, although cam slots may alternatively beconfigured such that proximal translation of cam pin 105 pivots jawmembers 110, 120 from the spaced-apart position towards the approximatedposition. The drive assembly is described in greater detail, forexample, in U.S. Pat. No. 9,655,673, previously incorporated herein byreference.

With continued reference to FIGS. 1 and 2A-2B, handle assembly 30includes a fixed handle 50 and an actuator, e.g., movable handle 40.Fixed handle 50 is integrally associated with housing 20 and movablehandle 40 is movable relative to fixed handle 50. Movable handle 40 isultimately connected to the drive assembly (not shown) that, together,mechanically cooperate to impart movement of jaw members 110 and 120between the spaced-apart and approximated positions to grasp tissuebetween electrically-conductive surfaces 116, 126, respectively. Morespecifically, pivoting of movable handle 40 relative to fixed handle 50from an un-actuated position towards an actuated position pivots jawmembers 110, 120 from the spaced-apart position towards the approximatedposition. On the other hand, when movable handle 40 is released orreturned towards the initial position relative to fixed handle 50, jawmembers 110, 120 are returned towards the spaced-apart position. Abiasing member (not shown) associated with movable handle 40 and/or thedrive assembly may be provided to bias jaw members 110, 120 towards adesired position, e.g., the spaced-apart position or the approximatedposition.

Referring again to FIG. 1, fixed handle 50 operably supports firstactivation button 92 thereon in an “in-line” position, wherein firstactivation button 92 is disposed in the actuation path of movable handle40, as detailed below. Fixed handle 50 further defines a tunnel 52providing access to an interior thereof, and a first latch component 54,e.g., a latch track, disposed within the interior of fixed handle 50 andaccessible via tunnel 52, as also detailed below. Second activationbutton 94 is disposed in any suitable position to facilitate manualactivation by a user. In embodiments, second activation button 94 may bepositioned on housing 20, e.g., as illustrated, to enable the user tohold instrument 10 and activate second activation button 94 with asingle hand. In other embodiments, second activation button 94 may bedisposed in another position on housing 20, or may be remote therefromsuch as, for example, incorporated into a footswitch (not shown).

Instrument 10 includes a selector 200 operably associated with movablehandle 40 to enable selective transitioning of instrument 10 between afirst, in-line activation configuration (FIGS. 3 and 4), and a second,latching, manual activation configuration (FIGS. 5 and 6). Selector 200includes an arm 210 pivotably coupled to movable handle 40 via a pivotpin 42 towards a first end 212 of arm 210 and extending to a second,free end 214. A second latch component 216, e.g., a latch pin, isdisposed towards second, free end 214 of arm 210. Arm 210 furtherdefines an activation surface 218. Selector 200 is movable, e.g.,pivotable relative to movable handle 40 about pivot pin 42, between afirst position, corresponding to the first, in-line activationconfiguration (FIGS. 3 and 4), wherein activation surface 218 isoperably positioned relative to first activation button 92 to enableactivation of first activation button 92 with activation surface 218upon sufficient actuation of movable handle 40, as detailed below, and asecond position, corresponding to the second, latching, manualactivation configuration (FIGS. 5 and 6), wherein second latch component216 is operably positioned relative to tunnel 52 and first latchcomponent 54 to enable passage of second latch component 216 throughtunnel 52 and into engagement with first latch component 54 to therebylatch movable handle 40 in the actuated position upon sufficientactuation of movable handle 40, as also detailed below.

The use of instrument 10 in both the first, in-line activationconfiguration (FIGS. 3 and 4) and the second, latching, manualactivation configuration (FIGS. 5 and 6) is described. For use in thefirst, in-line activation configuration, with reference to FIGS. 1, 3,and 4, arm 210 of selector 200 is moved to the first position such thatactivation surface 218 is operably positioned relative to firstactivation button 92. With arm 210 disposed in the first position, andwith movable handle 40 disposed in the un-actuated position such thatjaw members 110, 120 are disposed in the spaced-apart position,instrument 10 may be manipulated such that tissue to be grasped,treated, and/or divided is disposed between jaw members 110, 120.

Once tissue to be grasped, treated, and/or divided is disposed betweenjaw members 110, 120, movable handle 40 is moved from the un-actuatedposition to the actuated position to pivot jaw members 110, 120 to theapproximated position to grasp tissue therebetween. In the actuatedposition of movable handle 40, activation surface 218 of arm 210 ofselector 200 is disposed in close proximity to or in abutment with firstactivation button 92 but does not activate first activation button 92.Thus, in the actuated position, tissue is mechanically held between jawmembers 110, 120 without application of energy thereto.

When it is desired to treat tissue grasped between jaw members 110, 120,movable handle 40 is moved further towards fixed handle 50 from theactuated position to an activated position, wherein, since instrument 10is disposed in the first, in-line activation configuration, activationsurface 218 of arm 210 of selector 200 is urged into first activationbutton 92 to activate first activation button 92 and initiate the supplyof energy from generator “G” (FIG. 1) to jaw members 110, 120 (FIGS.2A-2B) to treat, e.g., seal, tissue grasped therebetween. Morespecifically, electrosurgical energy is conducted betweentissue-contacting surfaces 116, 126 and through tissue disposedtherebetween to treat, e.g., seal, tissue.

After treating tissue, or where it is only desired to cut tissue,trigger 82 of trigger assembly 80 may be actuated to advance knife 172of knife assembly 170 between jaw members 110, 120 (FIGS. 2A-2B) to cuttissue grasped therebetween.

Once tissue is treated and/or cut as desired, movable handle 40 isreleased or returned to the un-actuated position such that jaw members110, 120 are returned to the spaced-apart position, releasing the sealedand/or cut tissue. The above may then be repeated to treat and/or cutother tissue.

Referring to FIGS. 1, 5, and 6, for use of instrument 10 in the second,latching, manual activation configuration, arm 210 of selector 200 ismoved to the second position such that second latch component 216 isoperably positioned relative to tunnel 52 and first latch component 54.

With arm 210 disposed in the second position, and with movable handle 40disposed in the un-actuated position such that jaw members 110, 120 aredisposed in the spaced-apart position, instrument 10 may be manipulatedsuch that tissue to be grasped, treated, and/or divided is disposedbetween jaw members 110, 120.

Once tissue to be grasped, treated, and/or divided is disposed betweenjaw members 110, 120, movable handle 40 is moved from the un-actuatedposition to the actuated position to pivot jaw members 110, 120 to theapproximated position to grasp tissue therebetween. From the actuatedposition, movable handle 40 may further be moved towards fixed handle 50to a latched position, wherein second, free end 214 and second latchcomponent 218 of arm 210 extend through (or extends further through)tunnel 52 and into engagement with first latch component 54 such that,upon release of movable handle 40, movable handle 40 is returned to andlatched in the actuated position via the engagement of first and secondlatch components 54, 218, thereby latching jaw members 110, 120 in theapproximated position grasping tissue therebetween.

When it is desired to treat tissue grasped between jaw members 110, 120,with jaw members 110, 120 latched in the approximated position, secondactivation button 94 is manually activated to initiate the supply ofenergy from generator “G” (FIG. 1) to jaw members 110, 120 (FIGS. 2A-2B)to treat, e.g., seal, tissue grasped therebetween. However, movablehandle 40 need not be latched in the approximated position in order toenable application of energy to jaw members 110, 120. Rather, ifdesired, movable handle 40 may be held in the actuated position (withoutlatching) and second activation button 94 manually activated to initiatethe supply of energy from generator “G” (FIG. 1) to jaw members 110, 120(FIGS. 2A-2B).

After treating tissue, or where it is only desired to cut tissue,trigger 82 of trigger assembly 80 may be actuated to advance knife 172of knife assembly 170 between jaw members 110, 120 to cut tissue graspedtherebetween. Once tissue is treated and/or cut as desired, movablehandle 40 is once again moved from the actuated position to the latchedposition to disengage second latch component 218 from first latchcomponent 54 to enable movable handle 40 to return to the un-actuatedposition, thereby returning jaw members 110, 120 to the spaced-apartposition. The above may then be repeated to treat and/or cut othertissue.
